I like the ideas.Alright, I think I have a decent game concept for a management sim now that might work, and a couple of story premises:
1: You start out in Colussia as you do in Origins, and instead request a brothel or strip club as your reward, alongside retiring.
2: Alternative concept, the game is set in Egypt. Continues from the evil ending of the first game, with the hero as Pharaoh, having enslaved all three of the royal girls. To break their wills once and for all, you'll force them to be your whores.
3. in the kingdom the second game is set. You find the royal Egyptian trio as they drop in, decide to make them sell their bodies.
Another part of the idea being that whoring them out gains you easy cash and breaks them faster as they do filthy things, but it affects their prestige. Escorting missions gain you more money but are harder to get, especially if your girls are low prestige, but they can get you connections that can be useful. Keeping a girl as yours gives you a lot of personal prestige and you could possibly even romance them, but you lose out on a source of income.
I guess for Osira it would be footjobs.
Checked out the sim brothel wiki, and it looks similar to slave maker 3, so I think I get the gist of where you're headed gameplay wise. Maybe do some light area/building upgrades with a simple tech tree to specialize in certain areas. Like sex, tease, etc.
